INTELLECTUAL PROPERTY

The HRBP Process is covered by issued patents and patent applications, including U.S. patent #5,541,056 (entitled “Method of control of microorganism growth process,” Huntley et al., issued 7/30/96), relating to the use of PBRs.  The patent concerns a method for growing aqueous microorganisms in a transparent photosynthetic reactor wherein a turbulent flow regime is maintained.  This broad patent was held valid in U.S. federal court when a third party challenged it in the 1990s.

In addition, HRBP has a broad patent pending covering its unique dual cultivation process using both photobioreactors and open ponds.  The patent application was filed as an International Patent Application designating all PCT Contracting States.  The application was published on 1 February 2007 as WO 2007/013899.
